Description

Method, system and equipment for relieving braking of forced train

Technical Field

The invention relates to the technical field of trains, in particular to a method, a system and equipment for relieving brake of a forced train.

Background

When the train stops, the train braking system can keep the train braked so as to ensure that the train does not slide. When the train is started, the train brake can be relieved. When the brake system is in failure, the train runs with a brake to damage the brake shoes of the wheel pair, or the train keeps on a braking state to influence the departure of the train, which leads to late hours.

If the train has a person to drive, the train operator can relieve the brake manually, and the manual relief has two types, namely manually removing the guide frame and operating a brake relief button on the train. However, if the train is in the unmanned mode, if no train operator can manually relieve the train braking, the train will have a long time at a later time or the train operates with a brake, and the damage to the wheel set of the train is serious.

For an unmanned train, a forced train braking relieving instruction is generally sent to the train remotely to solve the problem of brake system faults, so that the brake which cannot be relieved normally is relieved, the damage of a brake shoe and a wheel set is avoided, or the train is guaranteed to operate in an alignment point. However, if the train is in a braking state, the forced braking relieving command is sent by mistake, so that the danger of train sliding can be caused.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings.

"upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

Based on the above, the embodiment of the invention provides a method for relieving braking of a forced train, which is applied to a terminal and used for sending a forced braking relieving instruction to the train through the terminal so as to solve the problem of train braking obstacle. Meanwhile, in order to avoid the danger of the train caused by mistakenly sending a forced braking relieving instruction to the terminal, a series of judgment steps are arranged at the terminal to avoid the danger caused to the train.

Referring to fig. 1, specifically, the method includes:

step S1: and receiving a brake release instruction of the forced train.

In the embodiment, a forced train braking relieving instruction is sent to the remote train through the terminal to relieve the braking of the remote train, namely when the remote train has a braking relieving obstacle, the terminal sends the forced train braking relieving instruction to the train, and the train relieves the braking according to the instruction. In this step, the terminal can control one train or a plurality of trains, and when a plurality of trains are controlled, entity buttons for relieving the brake of the forced trains which are in one-to-one correspondence with the trains are respectively arranged at the terminal, or the buttons for relieving the brake of the forced trains which are in one-to-one correspondence with the trains are respectively arranged on the terminal operation interface. When a compulsive train brake relieving instruction needs to be sent to the train, a compulsive train brake relieving button corresponding to the train on the terminal is operated, and the terminal receives the compulsive train brake relieving instruction at the moment.

For example, the terminal may send a train brake release command to train a, train B and train C, the terminal is provided with train brake release buttons corresponding to train a, train B and train C, when the train brake release command needs to be sent to train a, the train brake release button corresponding to train a is operated, and the terminal receives the train brake release command corresponding to train a.

Step S2: train braking information is acquired.

In the embodiment, a forced train braking relieving instruction is sent to the train in a remote mode through the terminal, at the moment, the terminal does not have train braking information, and when the terminal receives the forced train braking relieving instruction, the train braking information is obtained by sending the instruction to the train, so that whether the forced train braking relieving instruction is sent to the train or not is judged.

For example, the terminal receives a brake release instruction of a forced train corresponding to the train a, at the moment, the terminal sends a request for obtaining brake information of the train a to the train a, and the terminal obtains the brake information of the train a and judges the brake state of the train according to the information.

Step S3: and judging whether the train brake application quantity is greater than 2 or not according to the train brake information, if so, ignoring the forced brake release instruction, and if not, sending the forced brake release instruction to the train.

When the train is braked, the train does not slide, the braking quantity is randomly determined according to the stopping condition of the train, but the normal braking quantity of the general train is 4, which indicates that the train is normally braked, and if the train is normally braked, a forced braking relieving instruction is sent to cause danger. When the general train brake release is lost, at most one brake release fails, and the failure probability is relatively low, under the condition that the safety is first ensured, in the embodiment, it is assumed that if the train brake quantity is relatively large, the train is proved to be normally braked, and the transmission of a forced train brake release instruction can cause danger. Therefore, in the present embodiment, the braking number 2 is selected as the judgment criterion, and it is obvious that the braking number 2 is not the only judgment criterion.

In an alternative embodiment, the present invention provides a method for relieving braking of a forced train, further comprising: step S4:

Step S4 is before step S2, as described in the previous embodiment, the terminal is a remote train, and sends a forced braking mitigation command to the train, and before sending the forced braking mitigation command, the terminal first obtains the train operation mode, determines whether the train is in the unmanned mode, and if the train is in the unmanned mode, then executes step S3. If the train is not in the unmanned driving mode, the forced braking relieving instruction sent to the train is ignored, and the actual running condition of the train is judged more accurately by a train driver when the train is driven by a person, so that the judgment made by the train driver is used as the standard.

If the train running mode is a creeping mode, which proves that the train brake release fails, the train runs with a brake, the brake shoe of the wheel pair is damaged by the mode, and at the moment, a forced brake release instruction needs to be sent to the train.

In this embodiment, the method for relieving braking of a forced train provided by the invention further includes: step S5: and acquiring the closing state information of all doors and windows of the train, judging whether all the doors and windows are closed well, and if not, stopping sending a forced braking relieving instruction to the train. In the present embodiment, step S5 precedes step S2.

As described in the foregoing embodiment, the terminal needs to obtain all the door and window closing state information of the train from the train. Generally, when a train is in a braking state, the door and the window of the train are in an opening state, so that people can get on or off the train conveniently and air circulation is facilitated. However, when the train is in a non-braking state, all doors and windows of the train are in a closed state, so that the safety of passengers is ensured. Therefore, the purpose of this step is to further confirm whether the train is in a braking state or a braking mitigation state, that is, if all doors and windows of the train are in a closed state, it can be further determined that the train is not in the braking state, and a forced braking mitigation command can be sent to the train, and if not, the forced braking mitigation command sent to the train is ignored, and the purpose of this step is to further confirm the safety of sending the braking mitigation command.

In this embodiment, the method for relieving braking of a forced train provided by the invention further includes: step S6:

and judging whether the train brake application quantity is 0 or not according to the train brake information, and if so, ignoring the forced brake release instruction. After step S2.

In one case, if the train brake application quantity is 0, it is proved that the train has no brake obstacle and is in a normal running state, so that a forced train brake release instruction does not need to be sent to the train, and if the forced train brake release instruction is continuously sent, the complex judgment of a train CPU is increased.

In another case, the train brake application number is 0, if we get the train brake information before, in this case, the train is very likely to receive the next brake command sent by the train CPU, and at this time, if the brake release command is sent, it will also bring danger. If the braking instruction sent by the CPU of the train and the braking relieving instruction sent by the terminal arrive at the same time, the problem of complex judgment situation is added to the train. It is clear that the purpose of this step is to ensure the safety and necessity of the brake release command transmission.

For example, the terminal acquires the brake information of the train a at 8:00, the train braking number is 0, and the train a arrives at the station at 8:02 time according to the predetermined time schedule of the train a, and the train a acquires the brake command sent by the CPU of the train a. If the terminal does not ignore the brake release instruction sent to the train A under the condition that the brake number of the train A is judged to be 0, three conditions occur: in the first case A, the train receives a braking relieving instruction sent by the terminal before 8:02 cents; in the second situation A, the train receives a braking relieving instruction sent by the terminal in 8:02 time division; in the third case A, the train receives a brake release instruction sent by the terminal after 8:02 minutes. If the first condition is true, train A executes the brake release command first, followed by the brake command. If it is the second situation, the problem that the CPU of the train A judges the complex situation is increased. If the third condition, the A train will carry out braking earlier, carries out braking afterwards and alleviates, can let the A train that will brake originally and park begin to brake and alleviate, if someone gets on or off the bus or the train is in the upslope this moment, will lead to very big danger.

In this embodiment, the method for relieving braking of a forced train provided by the invention further includes: step S7: and acquiring train traction information, judging whether the traction can prevent the train from sliding, and if not, ignoring the forced braking relieving instruction. In the present embodiment, step S7 precedes step S2.

And (4) as the above steps, the terminal needs to acquire the train traction information, and if the train traction is enough to prevent the train from sliding, a forced relieving instruction is sent to the train. If the traction force of the train is not enough to prevent the train from rolling, the forced relieving instruction sent to the train is ignored, otherwise, the risk of rolling the train can be caused.

It is obvious that the magnitude of the traction of the train is not uniquely determined according to the difference of the parking environments of the train, for example, the traction of the train a is different when the train a stops at different slopes. It is obvious that in other embodiments, the above steps are not the only order of execution of the method, that is, the order of execution of the steps can be adjusted according to actual needs.
